CDCLVP111VFR

Overview

The CDCLVP111VFR is a low-skew clock buffer and driver manufactured by Texas Instruments. It features a 2:10 fanout ratio, distributing one differential clock input pair to ten differential LVPECL output pairs. The device supports multiple input standards including CML, LVDS, LVPECL, and SSTL, with a maximum operating frequency of 3.5 GHz. It operates on a supply voltage range of 2.375 V to 3.8 V and is housed in a 32-LQFP package (7x7 mm). The component is designed for surface mount installation and functions within an ambient temperature range of -40°C to +85°C.

Feature Summary

• 2:10 Fanout Ratio: Distributes a single differential clock input to ten differential LVPECL outputs.
• Wide Input Compatibility: Accepts CML, LVDS, LVPECL, and SSTL signal formats.
• High Frequency Operation: Supports clock frequencies up to 3.5 GHz.
• Low Skew Design: Optimized for minimum skew in clock distribution applications.

Applications

• High-performance clock distribution networks
• Driving 50-ohm transmission lines
• Multiplexing differential clock sources

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm packaging details such as tape and reel quantities or cut tape availability. Ensure the selected variant matches the required thermal and electrical specifications for the target application environment before finalizing procurement orders.

Selection Notes

Select this component when a 2:10 fanout with LVPECL outputs is required from mixed-format inputs like CML or LVDS. Confirm that the system power supply falls within the 2.375 V to 3.8 V range. Verify that the 32-LQFP footprint fits the PCB layout constraints and that the -40°C to +85°C operating temperature range meets the environmental requirements.

Part Context

This part belongs to the CDCLVP111 series of low-skew clock drivers. It is functionally related to other devices in the family that may offer different fanout ratios or output configurations, but specifically provides a 2-input multiplexer feeding into 10 LVPECL outputs.

Replacement Considerations

Check for pin-to-pin compatible alternatives such as MC100EP111, ES6111, LVEP111, or PTN1111 if direct substitution is needed. Verify that any replacement maintains the same 2:10 ratio and LVPECL output compatibility.
